Designed with microprocessor-controlled dual thermocouples, this stirring hot plate offers you accurate temperature control and protection from over-heating. Actual surface temperature is displayed in real time on an easy-to-read digital screen. Powerful magnets and motor provide stirring speeds of up to 2000 rpm and mixing capability of up to 15 L of liquid. The square plate design allows flexibility of vessel sizes and combinations. Up to four 250 mL beakers can easily fit on the surface at the same time. To keep you safe, a “hot” warning light flashes whenever the plate surface temperature is above 50°C and continues to flash until the temperature drops below 50°C, even when unplugged. The units also include BioCote antimicrobial protection which reduces the presence of odour and stain causing microbes such as bacteria, mould, and fungi on the product surface by up to 99.99%. Formulated from silver ion additives, BioCote provides built-in antimicrobial protection to support a more hygienic laboratory environment. Includes an integral fitting for a retort rod and allows the retort base to slide underneath. Features a coated aluminium top plate for rapid heating and better temperature uniformity. Please Note: BioCote® technology does not protect users or others against disease causing bacteria, germs, viruses, or other harmful organisms. This technology is not a substitute for good hygiene and/or cleaning practices.
